Effect of vent opening and insect screens on greenhouse microclimate distribution
(2006)
The objective of this work was to experimentally investigate the influence of vent type (side, roof or both) and of an anti-aphid insect screen on airflow and temperature distribution of a mono span greenhouse round arch ...
Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
(2008)
In the present study a commercial CFD code was used in order to investigate the dispersion of a pesticide inside an arch type tunnel greenhouse with continuous side vents. The greenhouse was cultivated with a tomato crop ...
Experimental results and spatial simulation of climate in a greenhouse with insect screens
(2011)
Aim of the present paper was to present, analyze and compare detailed experimental data and CFD simulation results in a greenhouse equipped with insect screens. The studied greenhouse was a round arch type with vertical ...
Measurements and modelling of tracer gas distribution in a naturally ventilated greenhouse for pesticide dispersion determination
(2006)
In this study numerical and experimental results concerning the dispersion of a tracer gas (N2O) inside an experimental greenhouse with a tomato crop were presented and analyzed. The proposed simulation concerns a greenhouse ...
Performance test of a Na+ accumulation model as part of a decision support system for closed hydroponic systems management
(2012)
The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ...
Case studies of a modified biological simulator (TOMGRO) according to short cropping period
(2012)
The aim of this work was to perform a sensitivity analysis of a modified biological simulator (TOMGRO) in tomato crop during winter period. The modified biological simulator (TOMGRO) that used for case studies of the ...
Test of a greenhouse covered by polyethylene film that reflects near-infrared radiation
(2012)
The aim of this work was to study the effects of a new polyethylene (PE) 'silver' film [with high reflection and absorption in the Near Infrared Radiation (NIR)] on greenhouse microclimate and on growth and production of ...
Study of a passive solar heating greenhouse crop grow gutter
(2011)
Water-filled transparent polyethylene tubes have been used as a passive solar system in greenhouses in Greece. In this work, the performance of a passive solar heating system used to serve as a crop grow gutter is studied. ...
